Pathetic internet service go with trusted brands

We got this rain sim card believing that this is a good option. They fast take the payment upfront up until now we can't use this simcard it keeps no sim card but if we put our sim cards it works. How can I pay for a dam service that doesn't f work being a medical professional I am dependent on helping patients via interactive consultation. There is call center or help center how the hell do you resolve this. Kindly ensure I get immediate assistance or Im going to charge you for failure to deliver on your contract
